英文摘要	Unique climatic characteristics and complex hydrochemical environments lead to freeze-thaw and chemical dissolution combining action, which is an important reason for the exfoliating and nick becoming shallow of the metamorphic sandstone carrier of the Helankou rock paintings. The mass, elastic wave velocity and uniaxial compressive strength of rock samples after 0, 15, 30, 45 and 60 freeze-thaw cycles respectively immersed in distilled water and Na2SO4, NaHCO3 or CaCl2 solution of 0.5 mol/L concentration were tested, and the damage characteristics of rock paintings carrier under the combined action of chemical and freeze-thaw were systematically explored. The cumulative damage mechanism was analyzed qualitatively and quantitatively by scanning electron microscopy(SEM), X-ray diffraction analysis(XRD) and the damage variable based on the change of the porosity. The results show that the rock samples present different degrees of cumulative damage in the process of freezing and thawing cycles under different conditions and that the damage is caused by the differences of the type, quantity and connection of the sample pore aroused by different combinations of frost heave, dissolution and salt crystallization. © 2019, Science Press.
